Overview
Preliminary RT9204/A Dual Regulators - Standard Buck PWM DC-DC and Linear Controller General Description The RT9204/A is a dual power controllers designed for high performance graphics cards and computer applications.
The IC integrates a standard buck controller, a linear regulator driver and protection functions into a small 8-pin package.
The RT9204/A uses an internal compensated voltage mode PWM control for simple application design.
An internal 0.
8V reference allows the output voltage to be precisely regulated to low voltage requirement.
A fixed 600kHz oscillator reduce the component size for saving board area.
The RT9204/A protects the converter and regulator by monitoring the output under voltage.
